Is (0,0) a solution of the system y>x and x+y>0?
olga55 [171]
Plug the values (x,y)=(0,0) into the inequalities:

y\ \textgreater \ x \\
0\ \textgreater \ 0 \\
not \ true \\ \\
x+y\ \textgreater \ 0 \\
0+0\ \textgreater \ 0 \\
0\ \textgreater \ 0 \\
not \ true

0 isn't greater than 0, no (0,0) is not a solution to either of these inequalities.

The answer is D.

Find the area A of the sector of a circle of radius 90 in formed by central angle 1/6 radian.
miv72 [106K]

Answer:

2121 in^{2} Rounded to the nearest inch.

Step-by-step explanation:

A = \pi r^{2}  Is the formula for a circle, but we only have a portion of a circle so we will have to adjust the formula for a part of the circle.

A = \frac{\frac{\pi }{6} }{2\pi } \pi r^{2}  The \frac{\pi }{6} is the part of the circle and the whole circle is 2\pi

\frac{\frac{\pi }{6} }{2\pi } is the same as \frac{\pi }{6}÷\frac{2\pi }{1} Which is the same as \frac{\pi }{6} x \frac{1}{2\pi } Which is the same a \frac{1}{12}

A = \frac{1}{12}\pi90^{2}

A = \frac{1}{12}(3.14)(90)(90) = 2119.5.  When you use the \pi on your calculator you get a slightly different number.  This is due to rounding.

A = 2120.575041

A person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen he sells it at Rs 80 a pair find the gain p
marusya05 [52]

Answer:

33.33%

Step-by-step explanation:

We need to calculate the <u>unit selling price and cost of each cosmetics.</u>

If a person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen., then for 1 cosmetics, we will say;

x = 1 cosmetic

since 360 = 12 cosmetic

cross multiply

12x = 360

x = 360/12

x = 30

Hence the unit cost price of the cosmetics will be Rs. 30

Similarly, if he sells it at Rs 80 a pair, then he sold one cosmetic at 80/2 = Rs. 40 (a pair is 2 cosmetics)

Selling price per unit = Rs. 40

Cost price per unit = Rs. 30

percent gain = SP-CP/CP * 100%

percent gain = 40-30/30 * 100

percent gain = 10/30 * 100

percent gain = 100/3

percent gain = 33.33%

Hence the percentage gain is 33.33%
